Abstract

A high voltage buffer module used in an input/output buffer circuit coupled between a high voltage circuit and a low voltage circuit, operates between a first supply voltage and its complementary second supply voltage. A pull-up module, coupled between the first supply voltage and an output node, outputs the first supply voltage to the output node, in response to an input signal. A voltage detection circuit provides the pull-up module with at least one bias voltage selected from a predetermined set of voltage levels, wherein the voltage detection circuit selects the bias voltage upon detecting a reduction of the first supply voltage.
